Science
Mechanism of Action
This ingredient functions as a high-performance humectant and non-occlusive film former. Its specific carboxymethyl and succinamide modifications enhance its water-binding capacity and solubility, allowing it to lock in moisture and significantly reduce trans-epidermal water loss (TEWL). Furthermore, it provides secondary benefits through free-radical scavenging antioxidant activity and mild antimicrobial properties by disrupting bacterial cell membranes.
Research
Clinical Evidence
High confidence1%
Key findings
- 01 Demonstrated superior fungal growth inhibition (0.30 cm vs 0.12 cm) compared to standard chitosan at a 1.0% concentration.
- 02 Hydrogel inclusion studies at 0.1-2.0% confirmed accelerated wound repair and enhanced fibroblast proliferation, supported by CCK-8 cell viability metrics.
Transparency
Dusting Analysis
Given its efficacy in wound repair and hydration starting at 0.1%, concentrations below this threshold are likely insufficient for the molecule's film-forming and moisture-binding benefits.
The Formula
Formulation
Stability
Highly versatile across a broad pH spectrum, remaining stable where native chitosan would precipitate. It maintains excellent compatibility with anionic and non-ionic surfactant systems.
Synergies
- Anionic surfactants
- Humectants
- Antioxidants
Conflicts
- Highly concentrated electrolytes
- Strongly cationic polymers
Safety
